COAL-MINE CAR.

Specification of Letters Patent.

Application led J une 29, 191-5. Serial No. 37,086.

T 0 all whom it may concern.'

Be it known that I, WALTER A. DoRsEY, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Coal-Mine Cars, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates .to improvements in the cars used for the haulage of coal from mlnes.

Such cars are subjected to exceedingly severe usage. The grades in the mines are frequently steep and the cars are subjected rst to severe pulling strains as they go up these grades, and then to severe pressure. And the grades are laid on short radii so that the cars and in fact entire trains are frequently thrown from the tracks.

In consequence of these hard conditions breakages of parts and the destruction of cars are frequent.

When they have been built up on the plans heretofore followed a breakage, even though it be of one of the minor parts, will frequently require that the entire car be set aside to await the repair of such brokenlpart. Blacksmith and machine shops are required at the mouths of the coal mines to meet the large amount of labor incident to keeping the cars in repair. Here they, often in large numbers, must await their turn to be taken to pieces and reconstructed, even in cases where only a minor part has been damaged or broken. Much of the expense incident to the operation of these coal mines is that incident to the tying up of the cars that are broken or impaired, or worn out, and frequently, just at the time when there is urgent demand for numerous cars at a coal plant there will be a serious hindrance to the output because of those that are tied up for shop work.

The object of this invention is to provide a car for use in coal mines which, first, will be so constructed that those parts which are subjected to the severest pulling and pressure strains and to lateral torsion can be made of metal and exceedingly strong, but light; and so that the detailed parts will be so related to each other and to the entirety that each of a number' can be built up of composite unitary elements which can be made as separate elements at the factory and can be kept in stock at the niines, any one of which elements can be quickly substituted for a corresponding impaired or broken one. Skilled mechanics are not needed to repair a car, the only labor required being the detaching of a few bolts,

inserting a new unitary element, and replacing the bolts.

The car which I have devised is illustrated in the drawings.

Fig. 14 is a perspective showing the several elements of the car detached from each other.

The base frame which receives all of the' pulling and pressure strains is indicated as an entirety by l. It is formed as a rectangular unitary steel casting, and with it are formed, integrally, the bumpers 2 or drawbars, coupling sockets 3, seats 4 for the axle boxes, sockets '5 for the center brackets of the side wall elements, and end sockets-6 and 6a to receive the front and rear brackets, and bearings 7 for the brake shaft.

Parts of this base frame are the strong steel sills 8, extending from end to end of the car, and also the integral cross girt'bars 10, the aforesaid draw bars or bumpers at 2 connecting the sills at the ends. These sills and girts are disposed in relation to each other and to the lines of strain and of bearings. i

torsion exerted upon the car in such way that, it is practically impossible, under any of the ordinary stresses to which it is subjected to distort the frame or break it.

The side sills 8 are formed with vertical flanges 11 and inwardly extending horizontal flanges 12. The upper surfaces of the flanges 12 coincide with the surfaces of the girts 10 and of the flanges 13 of the end cross bars. And upon the surfaces of these flanges and girts are laid the heavy planks 9 which form. the floor of the car, the upper surfaces of theplanks being approximately flush with the upper edges of the vertical flanges at the front and rear ends of the bottom casting.

Heretofore in coal mining cars the base frames have been made of timbers secured together in one way or another, and consequently those parts of the cars are liable to breakage from severe strains and twistings, the wooden timbers and planks which receive the strains not being successfully held in position. This is obviated in the present construction, as all of the parts that are in the plane of the lines of draft, are, as above described, formed of metal in one integral casting in the form of a frame extending continuously from end to end and from side to side of the oar, with its tension bars and reinforcements so disposed as to reduce to a-minimum the amount of metal required, and at the same time. present that metal tothe lines of strain and compression and transverse torsion.

This frame casting is formed with horizontally expanded plate-like parts at 13 to give extended and firm support to the axle 14 are the metal loops forming the top walls of the sockets 3 for the couplers, these loops being also cast solid with the base frame. 15 is an aperture in the loop and 16 a registering aperture in the integral frame below it for receiving the coupling pin 16a.

The side walls and end walls are formed as separate integers ready to be attached to or ldetached from the base structure.- Each 'side wall is formed with an upper outer part 17, a lower inner part 19, and an intermediate inclined part 18. At each rear corner of the car there is a bracket indicated as an entirety by 20, comprising an upper vertical bar 26, an inner bottom bar 27, and an inclined intermediate bar 28, these being arranged to provide a flange 21 extending lengthwise of the car and a flange`22 extending transversely and all of the'said parts 21, 22, 26, 27, and 28 are cast integrally together. At the lower ends of these brackets there are integral extensions or tenons 24 each provided with a lockreceiving aperture 25. In the flange 21 are apertures 29, and in flange 22 are apertures 30.

At the front end ofthe car there are two prising an outer top bar 32, an inner bottom bar 33 and an intermediate inclined bar 34, and having a vertical extension 35 at the top with a hmge bearing aperture 36. At the lower end there is an extension or tenon 38 with a lock-receiving aperture 39'. bAt 37 there are apertures in the bracket for olts.

There are two center brackets. Each is indicated by and has an upper outer bar 71, a lower inner bar 72 and an intermediate inclined part 73, the latter being formed with horizontal extensions 74. At the lower end of this bracket there is an extension or tenon 75 with a look-receiving aperture 76. The three brackets of each side section are connected together by planks 31a, 31h, 310, each being bolted at its rearend in the angle formed by the flanges 21 and 22 of. the rear bracket.' and bearing snugly against the outer flange 21 and against the parts 71 and 32 of the other brackets. Each plank 31b is secured to the intermediate or inclined parts of the brackets in a similar manner; and the lower plank 31c is secured planes of the car, which is outside of the' vertical longitudinal .plane of the inner l' lower bars, of the brackets, 27, 33 and 72. It will also be seen that the plank or side wall part 17 supported in the brackets is in vvertical longitudinal planes outside of the vertical longitudinal planes of the lower inner plank 19.

The rear wall of the car is indicated by 40, comprising a narrow section 42 and an upper tapering wider part 41. This is bolted firmly in place against the transverse anges 22 of the rear brackets. Its upper edge is reinforced and firmly held by a cross bar 44 which is at its ends secured by two of the bolts that pass through the bracket Hanges.

The bottom part of this end wall is snugly flush with the top surface of the plates or planks 9 secured to the base frame.

At the front end of the car there is a swinging gate, indicated as an entirety by 45, which is formed with an upper wider part 46 and a bottom narrower part 47. These parts are composed of plates or planks which are secured to vertical brace bars 48. These extend from the bottom of the gate to lines above the top, as at 49, and

, lower ends.

`mounted in the bearing apertures 36 in the are provided with hinge-eyes 50. These brace bars also have bearings 51 near their '52 is a hinge rod which is aforesaid extensions- 35 of the front brackets. Upon this rod are fitted the hinge loops 50. To-hold the gate firmly in position when elevated, spacer tubes 53 are in'- terposed between the hinges and the front corner brackets. 54 is a rock shaft for carrylng and operating the gate lock. It has a latch dog 55 adapted to engage with the latch pin 56 carried by one of the front body brackets. 57 is a lever secured to ,the shaft 54 and carrying a latch dog 58 adapted to engage with a companion latch part 58a -on the gate. v

59, 59 indicate the axles which are mounted in the bearings -59a secured in the bearing seats on theunder sides of the base frame. v60, 60 are the carwheels carried by the axles. 61 is afbrake block mounted in the longitudinal planes of the wheel rims and having concave surfaces. at 62 for engaging with the wheels. Each brake block is held in proper vertical lines by means ofgtuide rods 63 carried by the central bracket 70 and by the guide rods and guide plateA 64. 65 is a lever connected to the rocking brake shaft 66 mounted in the bearings 7 that are integral with the base frame. The short arm of the lever 65 is connected to the brake blocks by means of an arm 68. 77 is a ratchet bar bolted to the front corner bracket with which the lever engages to hold the brakes in their adjusted positions. i

The devices forlocking the tongues or tenons 25, 75 and'88 in the sockets 5, 6, and 6a may be bolts or pins held by cotter keys so as to be readily detachable.

From the above description it will be seen that I provide a mine car having a base frame,'sides and ends which are separately constructed unitary integers, any one of which can be quickly removed, and foiqv any one of-which another can be readily substituted without requiring skilled labor'or work in a shop. Yetthe parts are so constructed andrelated to each other thatwhen assembled and fastened together in the way described, a` car of much greater strength is provided than is the case with any of the coal mine cars now in use. 1

The' several composite elements, which when assembled -form a car, are separately built up at the factory from the detailed parts which are secured together to provide4 these unitary structures.- That is to say, the parts of each side wall are secured together to constitute the composite elements shown in Fig. 14, this being true also of the rear end wall, the front end wall, of `the frame and axles, and the wheels, which are shipped to the mines as separate units, or in 'sets in knock-down condition. -When they reach the mines they are assembled by labor of the simplest form, and are at once ready `may be regarded as practically indestructible, and notwithstanding accidents or breakages of the other parts, it is always ready for having new attachment units separably fastened to it.

The brake blocks are flexibly carried by and held to the base framewhich latter, in conjunction with the lever 65 and the car wheels, hold them in position, even though the side wall sections `are removed. And when a side wall is replaced the brake-guide elements thereon immediately fit into the companion guide element on `the brake and thereafter the detachable side wall furnishes the bracing and guiding for the brake block, which is lirmly held thereafter in true position. v

vThe sockets 5, 6, 6a are prolonged vertically so as to give elongated bracing for the tenons or tongues on the brackets.
